I have called tech support numerous times. I have opened two tickets (unresolved). Nobody has the slightest clue, nor will they acknowledge there is any problem. The problem is very simple. I do not receive incoming calls while on extended network. Outgoing calls are fine, text messages seem to be okay. I just cannot receive calls. No it is not a weak signal issue as Verizon is adamant about. Incoming calls just go straight to voicemail. I have an app called Signal Check Pro (Android). Very informative app for telling you what band LTE you are on, cell site info, what carrier, etc. The area I have the most difficulty with this issue is Brady TX and surrounding areas. Served by Five Star Wireless. The other area being anywhere we roam on US Cellular. Jacksonville IL, and also parts of Central Washington State. Outgoing calls are fine, texts are fine but Verizon will not acknowledge there is any problem. It is not my device. It does not need a soft reset. Been there done that to no avail. I have checked all settings, roaming on, even turned off advanced calling, etc, etc. I have two phones and I call each phone on the other device. Neither will receive a call from the other device while in these extended areas (Galaxy 8 and Galaxy 9). If anyone has ever had his issue, please feel free to comment. If anyone has any ideas how to correct this issue please help. Thank you.
